Hi Rachel:

1. 4.3. Usage of Extended Request Messages
Section 4.3 gives a clear usage of the extended request messages. The statement is good. Since this part is trying to demonstrate the benefits of using DISCONNECT and other extended messages, more description will be helpful here.
2. Section 3.2, the first sentence: “A peer may have the requirement to start streaming the content from some specific point of the content timeline.” Point or Points?
3. In both base draft and extended draft, we can see the “Per-Peer-ID Transaction State Machine” figure. Section 2.4 of PPSP base tracker protocol indicates that the START state is transient. I don’t know whether it is suitable to mark “Transient” just next to the “PEER REGISTERD state” block.

Best Regards!
